Title: Method and device for calibrated frequency modulation phase locked loop
Inventor: MCCOLLOUGH KELVIN E
IPC: H03C3/09
Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To make the ratio of frequency modulation constant regardless of the magnitude of a system clock frequency in a frequency modulation phase locked loop (FMPLL). SOLUTION: The frequency of the FMPLL 100 is controlled by using a current controlled oscillation (ICO) 126. The ICO introduces a feedback to maintain a fixed gain and receives a current signal. The ICO related to the FMPLL generates a predictable change of an output frequency with respect to a certain change in the input control current (ICTL). A frequency shift can be generated by adding an additional delta current (IMOD) to the input control current while depending on the fixed gain. A clock that is subjected to frequency modulation is generated in an output of the ICO 126 by periodically changing the magnitude of the current IMOD. The magnitude of the IMOD controls the frequency shift quantity of the frequency modulation clock.
